Some very effective organic pesticides/fungicides are bacteria. Two examples are Bacillus thuringiensis israelensis for larvae that feed on roots[1] and Bacillus amyloliquefaciens, which out-competes soil pathogens[2] and prevents powdery mildew on foliage.[3] Research in this area is an important step toward learning how to build healthy soil instead of killing it.
